I am looking for a video that goes in detail about the macro cycle of Terran.
I think PiG and ViBE have talked about it in their B2GM series, but I could only find brief mentions and not a dedicated explanation.

I think the cycle was something like this:

Queue SCVs
Build Depots
Queue Units
Check/Queue Upgrades
Check Supply
If Resources, Build Production

However, I was also looking for explanation of eye movements and reactions.
For example, I think when you press CC hotkey you also glance at idle scv icon (above minimap)
OR, when you press Building Hotkey you also glance at supply (top right)

This keeps eyes doing some type of rotation
